Im going to go out on a limb and say that Galen Rupp is going to win the 5000 at Worlds. Yes, I know he hasn't been in form as of late but his mentality is to go after the world record every time. His form is the best in the world hands down. 12:37 is in danger of being taken down after the almighty Rupp does his thing. Farah and co have no chance of stopping him. From what I've been told he's been struggling with an infection but he's fine now and will run sub 12:30. It might have been an STD not an infection idk.
